CASEMENT WINDOW.

Application filed March 8, 1929. Serial No. 345,262.

This invention relates to casement windows. The principal objects of the present invention are to produce a strong and rigid' and render easy the application of such strips thereto. The invention consists principally in the weatherstripped metal casement window; and it also consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed. a

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur,

"Fig. 1 is an exterior side view of a weatherstripped casement window embodying my invention;

Fig. 2 is a vertical cross-section through the window on the line 22 in Fig. 1;

Fig. 3 is a horizontal cross-section through one side of the window. frame and the adjathereon, the section being taken on the line 3--3 in Fig. 1; and

Fig. 4 is a horizontal cross-section through the meeting rails of the sashes of said casement window.

Referring to the accompanying drawings, the invention is illustrated in connection with a double casement window comprising a ;metal window casing orframe A and two metal window sashes B that are secured to the respective jamb members of said frame by means of hinges 1 so as to swing outwardly.

The window frame A comprises metal q'amb members 2 connected at their upper ends by a metal head member 3 and at their lower ends by a metal sill member 4: Each of the j amb members 2 of the window frame preferably comprises a main body portion of substantially fiat-section having its inside and outside marginal edges shaped to form ornamental beads or moldings 5. Each jamb member .2 1s also provided on its sash supporting face with an outstanding lengitudinal flange 6 adapted, in the closed position of the sash hinged on said jamb memher, to overlap the outside edge of the inner side rail of said sash. The flange 6 of each amb member 2 is of substantially L-shaped section; that is, it comprises an outstanding web portion formed integral with the jamb member and provided at its outer edge with a rearwardly extending lateral flange adapted to form a vertical channel or recess ,7

adjacent to the outside face of the inner side rail of said sash.

The head member 3 of the window frame A preferably comprises a main body portion which extends horizontally from jamb to jamb and is provided along its inside and outside edges with ornamental beads or moldings 8 similar to the ornamental beads or moldings 5 along the inside and outside edges of the two j amb members 2. The main body portion of the head member is 7 upwardly offset adjacent to the upper outside corners of the sashes to form a longitudinal channel 9 in the underside of said head member. A metal strip 10 has a horizontal base flange secured in said channel means of screws 11 and is provided along its outside marginal edge with a downwardly and outwardly inclined flange which constitutes a drip edge.

The sill member 4 of the easementwindow frame A comprises a metal member of substantially inverted channel-shaped section which extends horizontally from jamb member to jamb member. The outer portion 12 of the web of the sill member 4; slopes downwardly to provide for drainage; and the inner portion of said web is offset-upwardly and is provided along its outer edge with an outwardly extending horizontal flange 14 that is spaced above and overhangs the inner marginal portion of the sloping portion 12 of the web of said sill member.

Secured to the sash opposing faces of the head, sill andjamb members of the easement window frame adjacent to the inside faces of 100 the sashes are metal sash stops of moldings 15 of substantially channel-shaped cross-section. The: channel-shaped stops 15 are positioned on the head, sill and jamb members of the window frame withtheir channels 105 facing the sash opposing faces of said 'mem-' bers and with their inside flanges seated within longitudinal grooves 16 provided therefor in said members. The steps 15 are 'clamped to the head, sill and jamb members 1 with their inside flanges seated within the longitudinal grooves 16 provided therefor .by means of fastening screws 17. At the sash opposing side of the stops the webs thereof are extended, as at 18, outwardly be- 0nd the outer flanges thereof to form a ongitudinal recess 19 adjacent to the inside faces of the top and'side rails ofthe sashes.

The frame members 20 which form the top bottom and side rails of the v) window sashes B are of substantially channel-shaped panes 22 are set in putt 24. The upwardly opening channels in the frame members which form the top rails of the sashes are closed by means of cover plates 26 that are rigidly secured to the webs of the top rails by means of screws27. The channels in the outer side rails -ofthe two sashes B are closed by means of metal membars 28 of substantially T-shaped cross-sec tion which form the meeting rails of said sashes. The stems of the T-shaped meeting rails 28 cover the channels in the outer side rails of the respective ashes and are rigidly secured thereto by screws 29. The T-shaped meeting rails are positioned on the respective sashes with the inner side flange of one meeting rail overlapping the outside face of the outer side rail of one sash and with the inner side flange of the other meeting rail overlapping the inside face of the outer side rail 0 the other sash. With this arrange:

ment of the T-shaped meeting rails the outer side flange ofthe rail on one sash overlaps the outer side rail of the other sash in the closed position of said sashes. The outside flanges of the bottom rails of the sashes terminate'at their lower edges in inwardly extending portions 30 which extend beneath the outwardly extending flange 14 of the sill member 1 of the window frame in the closed position of said sashes.

'The joint between the top rails of the sashes B and the. head member 3 of the window frame A is rendered Weatherproof and dustproof by means of a Weatherstrip 31 secured to the underside of said head member. Said Weatherstrip preferably comprises a strip of resilient sheet metal whose cute-1 side marginal portion is doubled under to provide a-sealing flange 32 adapted to resiliently engage the top surface of said cover plates 26 for the top rails of the sashes. The head strip 31 has its outer margin offset upwardly and clamped within the channel 9 of the head member 3 by means of the drip strip 10. The inner marignal portion of the head strip is bent downwardly and thence rebent upwardly to provide a sealing flange 33 which fits within the longitudinal recess 19 in the outside face of the head stop 15 and is adapted to resiliently engage the adjacent inner faces of the top rails of the sashes in the closed position thereof.

The joints between the window jambs 2 and the inner side rails of the sashes are weatherproofed by means of weatherstrips 34 secured to the sash opposing faces of the 'ambs in position to cooperate with the inner side rails .of the sashes in the closed positions thereof. Each of the jamb strips 2 preferably comprises a sheet of resilient sheet metal Whose inner side marginal portion is doubledback on the inner face of the strip and is thence bent outwardly away from the body portion of the strip and is thence 'rebent towards said body ortion to rovide a sealing flange 35, which fits wit in the lon itudinal recess 19 in the outside face of the jamb stop 15 and resiliently engages the inside face of the inner side rail of the sash in its closed position. The logitiidinally doubled inner side marginal portion of the jamb strip 34 extends beneath i I i at its outer side edge in a sealing flange 37' which is disposed at an oblique angle to the face of the jamb in position to resiliently engage the edge of the outside flange of the inner side rail of the sash in the closed position thereof. The free outer edge of the sealing flange 37 of the j amb strip fits loosely within the longitudinal recess 7 formed by the L-shaped flange 6 on the jamb member and is thus concealed and protected by said flange. J

The joint between the bottom rails of the sashes and the sill member 4 of the window frame is sealed by means of a Weatherstrip 38 comprising a resilient strip of metal which rests flatwise on the upper surface of the outwardly projecting flange 14 of said sill member and is provided along its outside cdge with a doubled-under sealing flange 39 which extends beneath said overhanging flange in position to resiliently engage the inwardly extending portions 30 at the lower edgesof the bottom rails of the sashes in the closed positions of the latter. The flat body portion of the sill strip 38 is firmly clamped down uponthe outwardly projecting flange 14: of the sill member 4 by means of a clamping plate 40 which is secured in position by screws 41.

The joint between the T-shaped meeting rails 28 of the sashes is sealed by means of a Weatherstrip 42 comprising a resilient strip of metal of substantially Z-shaped crosssection. The meeting rail strip 42 is mounted on the meeting rail of one sash with its web portion disposed opposite the stem por-' tion of said rail and with one flange 43 secured to theinside face of said rail and with the other flange located back of the outer flange of said rail and left free to form a sealing flange 44. With this arrangement of meeting rail strip when the sashes are closed the resilient sealing flange 44 of said strip bears-against the inside face of the outer flange of the meeting rail to which it is secured and against the adjacent outside corner of the meeting rail of the other sash thereby sealing the joint between said sashes.-

The hereinbefore described weather stripped casement window has numerous advantages. tion of air through the window; and it also serves to conceal and protect the sealing flanges of the Weatherstrips. It utilizes a maximum number of frame members of the same cross-sectional size and shape, thereby reducing to a minimum the number of specially formed frame members required to a window; and it minimizes the time and expense of appl ing the weatherstrips.
